Nightmare Alley is a 1947 American film noir directed by Edmund Goulding from a screenplay by Jules Furthman. Based on William Lindsay Gresham's 1946 novel of the same name, it stars Tyrone Power, with Joan Blondell, Coleen Gray, and Helen Walker in supporting roles. Power, wishing to expand beyond the romantic and swashbuckler roles that brought him to fame, requested 20th Century Fox's studio chief Darryl F. Zanuck to buy the rights to the novel so he could star as the unsavory lead "The Great Stanton", a scheming carnival barker.

Edmund Goulding was a British screenwriter and film director. As an actor early in his career he was one of the 'Ghosts' in the 1922 silent film Three Live Ghosts alongside Norman Kerry and Cyril Chadwick. Also in the early 1920s he wrote several screenplays for star Mae Murray for films directed by her then husband Robert Z. Leonard. Goulding is best remembered for directing cultured dramas such as Love (1927), Grand Hotel (1932) with Greta Garbo and Joan Crawford, Dark Victory (1939) with Bette Davis, The Constant Nymph (1943) with Joan Fontaine, and The Razor's Edge (1946) with Gene Tierney and Tyrone Power. He also directed the classic film noir Nightmare Alley (1947) with Tyrone Power and Joan Blondell, and the action drama The Dawn Patrol. He was also a successful songwriter, composer, and producer.
